| * | | Issue #25003: On Solaris 11.3 or newer, os.urandom() now uses the getrandom()Victor Stinner2015-10-011-15/+34
| | | | | | | | | | | | | | | | | | | | | | | | function instead of the getentropy() function. The getentropy() function is blocking to generate very good quality entropy, os.urandom() doesn't need such high-quality entropy.
* | | | Fix _PyTime_AsTimevalStruct_impl() on OpenBSDVictor Stinner2015-10-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | On the x86 OpenBSD 5.8 buildbot, the integer overflow check is ignored. Copy the tv_sec variable into a Py_time_t variable instead of "simply" casting it to Py_time_t, to fix the integer overflow check.
* | | | Backout change 28d3bcb1bad6: "Try to fix _PyTime_AsTimevalStruct_impl() onVictor Stinner2015-09-301-3/+2
| | | | | | | | | | | | | | | | | | | | OpenBSD", I'm not sure that the change was really needed. I read the test result of an old build because the OpenBSD was 100 builds late.

| | | | | | | | | | | | | | | | It looks like the check for integer overflow doesn't work on x86 OpenBSD 5.8.

| * | | Issue #25155: Fix _PyTime_Divide() roundingVictor Stinner2015-09-181-3/+8
| | | | | | | | | | | | | | | | | | | | _PyTime_Divide() rounding was wrong: copy code from Python default which has now much better unit tests.
| * | | Issue #25155: Add _PyTime_AsTimevalTime_t() functionVictor Stinner2015-09-181-38/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Windows, the tv_sec field of the timeval structure has the type C long, whereas it has the type C time_t on all other platforms. A C long has a size of 32 bits (signed inter, 1 bit for the sign, 31 bits for the value) which is not enough to store an Epoch timestamp after the year 2038. Add the _PyTime_AsTimevalTime_t() function written for datetime.datetime.now(): convert a _PyTime_t timestamp to a (secs, us) tuple where secs type is time_t. It allows to support dates after the year 2038 on Windows. Enhance also _PyTime_AsTimeval_impl() to detect overflow on the number of seconds when rounding the number of microseconds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overflow test in test_FromSecondsObject() fails on FreeBSD 10.0 buildbot which uses clang. clang implements more aggressive optimization which gives different result than GCC on undefined behaviours. Check if a multiplication will overflow, instead of checking if a multiplicatin had overflowed, to avoid undefined behaviour. Add also debug information if the test on overflow fails.

* | | | test_time: rewrite PyTime API rounding testsVictor Stinner2015-09-091-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop all hardcoded tests. Instead, reimplement each function in Python, usually using decimal.Decimal for the rounding mode. Add much more values to the dataset. Test various timestamp units from picroseconds to seconds, in integer and float. Enhance also _PyTime_AsSecondsDouble().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | datetime.datetime now round microseconds to nearest with ties going to nearest even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards -Infinity (ROUND_FLOOR). pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix also _PyTime_Divide() for negative numbers. _PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing rounding modes.

It occurs sometimes each month on a Debian buildbot slave running in a VM. The problem is that Python cannot do anything useful if a monotonic clock goes backward. It was decided in the PEP 418 to not fix the system, but only expose the clock provided by the OS.
